Sportsbooks set initial lines based on their own analysis, while this market’s odds are driven by supply and demand as traders buy and sell contracts. It's common to see discrepancies, especially before significant events or when new information emerges. Examining these differences can be insightful, as they may indicate where the crowd believes sportsbooks are over or underestimating the probability of a particular outcome.
